Title: Digital phase locked loop stabilization circuitry
Inventor: DEMMER WALTER HEINRICH
IPC: H03L7/00
Filed: 1987-03-27
Granted: 1996-07-25
Abstract: As used in a digital television receiver the invention includes a first phase locked loop which develops a sampling clock signal (CK) that is locked to the horizontal line synchronizing signals components of a composite video signal. A second digital phase locked loop is clocked by the sampling clock signal and develops a digital signal that is phase locked to the color burst signal. This signal is used as a regenerated color subcarrier signal to synchronously demodulate the chrominance components of the composite video signal into I and Q color difference signals. To compensate for frequency instabilities in the regenerated subcarrier signal caused by frequency instabilities in the line-locked clock signal, a third digital phase locked loop (300) develops an oscillatory signal (from oscillator 302) which is phase locked to a reference signal generated by a crystal controlled oscillator (310). A control signal (C') from the third phase locked loop is applied to circuitry (329, 338) which develops a control signal (C'') that is independent of the crystal frequency. This control signal is applied to modifying means (328) in the second phase locked loop to substantially compensate for frequency instabilities related to the clock signal. Since the control signal applied to the second phase locked loop is independent of the frequency of the control, there is no need for manual adjustment of the crystal oscillator.
